Pluchea camphorata is similar to P. odorata and rarely may hybridize with it. In P. camphorata, the phyllaries of the inner 2–3 series are thin and nearly translucent, lanceolate, and more than twice as long as deltate-ovate phyllaries of the outer series. The inner may be glandular but they are otherwise glabrous, prominently different in vestiture from the outer. The phyllaries of P. odorata are more strongly graduated and the inner are glandular and also clearly puberulent as well.
